I'm trying to get asterisk to proxy h263 for a video call, but not having any luck. I have posted a full call trace here: http://pastebin.com/d330aecb5 While watching a full packet dump on the asterisk node, I can see the h263 coming in from the clients, but it never leaves (asterisk never originates 1 h263 packet). You can see on line 123 of the pastebin that the calls get setup without video but then h263 is renegotiated on line 456. The second end point sets up h263 on line 313. I'm pretty lost as to how I can get asterisk to play nice. This is Asterisk 1.4.18.1 my sip conf looks like the following: [general] type=friend host=dynamic context=incoming srvlookup=yes canreinvite=no videosupport=yes qualify=yes nat=yes host=dynamic ; This device registers with us disallow=all ;better for custom-tunning codec selection allow=ulaw allow=alaw allow=h263 ; H.263 is our video codec allow=h263p ; H.263p is the enhanced video codec dtmfmode=rfc2833 ; inband is not supported in compressed codecs like gsm, so we better set it to rfc2833 [miles_8920_lap] type=friend host=dynamic secret=***** context=internal_devices ; the internal_devices context controls what we can do mailbox=8920 at sixsquares callerid= Miles Scruggs <8920> canreinvite=no [jon_8926_desk] type=friend host=dynamic secret=***** context=internal_devices mailbox=8926 at sixsquares callerid=Jonathan Larsen <8926> canreinvite=no -------------- next part -------------- An HTML attachment was scrubbed...
